The site was a major source of flint found at archaeological sites across North America, and has been estimated to be a mine source of the material from 11,000 BCE to 1600 CE. The site was designated a National Historic Landmark in 2011.〔(NPS NHL list for North Dakota )〕〔(【引用サイトリンク】publisher=Midwest Archeological Center )〕 Knife River flint was a prized toolmaking material among North America's prehistoric population, as it is particularly easy to work into projectile points, knives, and scraping tools. Materials from Knife River quarries have been found at prehistoric archaeological sites in northern Canada, New York, and New Mexico, and would have been traded by area tribes for other materials such as shell, obsidian, cloth, and (in the early European contact period) metal weapons.〔(【引用サイトリンク】title=Knife River Indian Villages National Historic Site: Geologic Resources Inventory Report )〕 The Lynch site, whose known extent is at least has an estimated 20,000 pits from which flint was quarried.
